30′′ Carbon Steel Sand Media Filter for Irrigation System

BALDR sand media filtration system is composed of one or more standard filter sand cylinder units. The filter mediais used to effectively remove suspended material and reduce turbidity.The system is equipped with three -way back flushing control valve, and the automatic controller can realize multiple sand cylinders to flush each other, and the water supply can be continuously supplied, then the automatic unattended water filtration system is formed.Each cylinder is equipped with aunique water distributor and water collector, and the filter sand layer works smoothly, the filter water is uniform and the flow is large.The shallow media filter system is especially suitable for the filtration of suspended objects, which can be used in conjunction with the high-precision disc filter or screen filter in the end to achieve the perfect filtering effect.

TYPICAL APPLICATION

Irrigation water: irrigation and fertilization, lanscaping ,municipal greening og golf course.

Industrial water: the purification filtration for production and confgiguration water and production recycled water.

Lanscape leisure: water filtration and composition increase or decrease for the fountaions, water scenes, water surtain, swimming pool, water park etc.

Raw water treatment: river water, lake water, sea water and other surface water filtration.FEATURES AND ADVANTAGE

High filtration rate, low pressure loss, large filtration water, especially the filtration effect for suspended floating objects in waterModular design, can be installed according to the flow requirement, theoretically can expand arbitrarily;The system filter unit has 16 (400mm) to 60 (1500mm) specifications, and various installation methods are available.Carbon steel material is treated by phosphating, electrostatic spraying, good corrosion resistance, can be installed indoor and outdoor, long service life;The system controller has built-in computer chip, the water pressure sensor collection and program setting can realize automatic control of unattended.online automatic backflush of dirt and impurities, take turns cleaning each unit and continuously filter the water supply.The selected quartz sand or garnet can be used as the filter medium, and the size of the filter media can be selected according to the water quality.The minimum diameter of 0.16mm can be selected as the homogeneous filter material.It can be convenient to observe the internal situation,humanized design of access port, clean and service at any time, easy maintenance

THE COMPOSITION OF FILTRATION SYSTEM

The filter system consists of filter unit, three-way recoil filter valve, automatic back flushing controller and other major components, and to connect with Y-type filter, air valve, pressure gauge, main pipe, support frame and other spare parts ,the filter unit is filled with the appropriate filter media.
BALDR SAND MEDIA FILTER PROVIDES TWO SERIES OF SINGLE-CHAMBER AND DOUBLE-CAVITY CONFIGURATIONS

WORKING PRINCIPLE

SYSTEM WATER FILTRATION STATE

Under the control of the automatic controller, when the whole system are in the filter state, the sewage enter with the high pressure, through aunique water distributor to keep the water distribution filter sand smooth, the flow of laminar flow through the filler layer, Impurities are trapped in the filler layer.Through the bottom of the distribution of multiple water collectors, Filtered can clean water ,evenly collected through the outlet pipe out. The advection filter allows the filter to operate at high flow rates.

SYSTEM BACKFLUSHING STATE

As the impurities accumulate in the filter medium, the pressure loss increases, and when the differential pressure increases to acertain setting value or reaches the setting cleaning time, the system automatically switches to the backflush state. The pressurized water enters the filter medium through the water collecting device, flushes it, separates the trapped contaminants and discharges the filtration system through the sewage outlet. The backflushends after2 minutes, the recoil control valve returns to the filter state, then the rinsed filter tank continues to enter the filter working condition. The automatic controller issues an instruction to start the backflush process of the next filter sand column ,until all the filter cylinders are rinsed again.
